undefined reference to symbol 'dlopen@@GLIBC_2.2.5'

Hi all,

I've opened this new topic because it's not the same as this one, but very similar.

Code: Select all

I'm very sad because I can't fly any more.

dear friend,

You can run flightgear with fgx or fgo as you are using download_and_compile.sh script, the error is well known but no one is interested to fix.
so use run_fgx.sh or run_fgo.sh to run fgfs .... and see you soon somewhere in the sky

Hi,

Thank for your answer, I've succeeded in compiling and launching Fgo, but fgfs isn't compiled because of this error message.

I've read some threas here but haven't found or undertsood how to do to have fgfs without that fgadmin.

I'll keep on reading...

With Ubuntu 13.04 amd64 I have exactly the same problem, but when I compile with Ubuntu 32-bit compilation could without problems. I do not know how to compile!

It seems to have solved the problem !

Reading another post http://www.flightgear.org/forums/viewtopic.php?f=45&t=19743 I noticed that the file libfltk1.3-dev does not must be installed! For this you need to run the command:

Code: Select all

sudo apt-get remove libfltk1.3-dev


.

Once that was done, the system compiles perfectly
If you are using to compile the spcript: download_and_compile.sh must avoid that the script loads the file. For this there are two possibilities:

1. Prevent automatic loading of dependencies, modifying the script as follows:

Code: Select all

APT_GET_UPDATE = "n"
DOWNLOAD_PACKAGES = "n"


2. Remove from the DISTRO_PACKAGES = file libfltk1.3-dev libfltk1.3 and the next parameter UBUNTU_PACKAGES = remove the file libfltk1. 3-dev libfltk1.3

However, I wish that whoever wrote this handy script, can remedy the problem

for this, please get in touch with brisa or one of the other d&c/fgmeta maintainers (such as callahanp) and provide your feedback/patches for consideration/review.

Hi,

I'm trying at the same time... and it seems to work!

Fgfs has compiled.

Thanks a lot for that answer!

Regards.

This is one way to fix it, with using libfltk1.3-dev:

https://gitorious.org/~hof/fg/hof-fligh ... 415b867c0b

Patch checks if the system supports libdl and if so, adds it to the library list.

Cheers,
Hof

Hi,

I'll try this patch next time... I just want to enjoy FG now!

Regards.
